      This explains, in real terms, why I've had so much struggle with online reading! Very interesting article.
  • Because of these preferences—and because getting away from multipurpose screens improves concentration—people consistently say that when they really want to dive into a text, they read it on paper

      This is backed up by a recent article: Faris, Michael J., and Stuart A. Selber. "E-Book Issues In Composition: A Partial Assessment And Perspective For Teachers." Composition Forum 24.(2011): ERIC. Web. 31 Mar. 2013.
  • Surveys and consumer reports also suggest that the sensory experiences typically associated with reading—especially tactile experiences—matter to people more than one might assume.

  • When reading a paper book, one can feel the paper and ink and smooth or fold a page with one's fingers; the pages make a distinctive sound when turned; and underlining or highlighting a sentence with ink permanently alters the paper's chemistry.
  • discernible size, shape and weight.
  • Although many old and recent studies conclude that people understand what they read on paper more thoroughly than what they read on screens, the differences are often small. Some experiments, however, suggest that researchers should look not just at immediate reading comprehension, but also at long-term memory.
  • When taking the quiz, volunteers who had read study material on a monitor relied much more on remembering than on knowing, whereas students who read on paper depended equally on remembering and knowing.
  • E-ink is easy on the eyes because it reflects ambient light just like a paper book, but computer screens, smartphones and tablets like the iPad shine light directly into people's faces.
  • the American Optometric Association officially recognizes computer vision syndrome.
  • People who took the test on a computer scored lower and reported higher levels of stress and tiredness than people who completed it on paper.
  • Although people in both groups performed equally well on the READ test, those who had to scroll through the continuous text did not do as well on the attention and working-memory tests.
  • Subconsciously, many people may think of reading on a computer or tablet as a less serious affair than reading on paper. Based on a detailed 2005 survey of 113 people in northern California, Ziming Liu of San Jose State University concluded that people reading on screens take a lot of shortcuts—they spend more time browsing, scanning and hunting for keywords compared with people reading on paper, and are more likely to read a document once, and only once.
  • When reading on screens, people seem less inclined to engage in what psychologists call metacognitive learning regulation—strategies such as setting specific goals, rereading difficult sections and checking how much one has understood along the way

How Big Data Is Taking Teachers Out of the Lecturing Business: Scientific American - 1 views

  • Any accurate evaluation of adaptive-learning technology would have to isolate and account for all variables: increases or decreases in a class's size; whether the classroom was “flipped” (meaning homework was done in class and lectures were delivered via video on the students' own time); whether the material was delivered via video, text or game; and so on. Arizona State says 78 percent of students taking the Knewton-ized developmental math course passed, up from 56 percent before
  • in Japan, where it is common for managers who have studied English with the adaptive-learning software iKnow to list their iKnow scores on their resumes.
  • “The reality is that it's going to be done,” says Eva Baker, director of the Center for the Study of Evaluation at the University of California, Los Angeles. “It's not going to be a little part. It's going to be a big part. And it's going to be put in place partly because it's going to be less expensive than doing professional development.”

The Reading Brain in the Digital Age: The Science of Paper versus Screens - Scientific ... - 25 views

  • The matter is by no means settled. Before 1992 most studies concluded that people read slower, less accurately and less comprehensively on screens than on paper. Studies published since the early 1990s, however, have produced more inconsistent results: a slight majority has confirmed earlier conclusions, but almost as many have found few significant differences in reading speed or comprehension between paper and screens. And recent surveys suggest that although most people still prefer paper—especially when reading intensively—attitudes are changing as tablets and e-reading technology improve and reading digital books for facts and fun becomes more common.
  • Compared with paper, screens may also drain more of our mental resources while we are reading and make it a little harder to remember what we read when we are done. A parallel line of research focuses on people's attitudes toward different kinds of media. Whether they realize it or not, many people approach computers and tablets with a state of mind less conducive to learning than the one they bring to paper.
  • Both anecdotally and in published studies, people report that when trying to locate a particular piece of written information they often remember where in the text it appeared. We might recall that we passed the red farmhouse near the start of the trail before we started climbing uphill through the forest; in a similar way, we remember that we read about Mr. Darcy rebuffing Elizabeth Bennett on the bottom of the left-hand page in one of the earlier chapters.

  • At least a few studies suggest that by limiting the way people navigate texts, screens impair comprehension.
  • Because of their easy navigability, paper books and documents may be better suited to absorption in a text. "The ease with which you can find out the beginning, end and everything inbetween and the constant connection to your path, your progress in the text, might be some way of making it less taxing cognitively, so you have more free capacity for comprehension," Mangen says.
  • An e-reader always weighs the same, regardless of whether you are reading Proust's magnum opus or one of Hemingway's short stories. Some researchers have found that these discrepancies create enough "haptic dissonance" to dissuade some people from using e-readers. People expect books to look, feel and even smell a certain way; when they do not, reading sometimes becomes less enjoyable or even unpleasant. For others, the convenience of a slim portable e-reader outweighs any attachment they might have to the feel of paper books.
  • In one of his experiments 72 volunteers completed the Higher Education Entrance Examination READ test—a 30-minute, Swedish-language reading-comprehension exam consisting of multiple-choice questions about five texts averaging 1,000 words each. People who took the test on a computer scored lower and reported higher levels of stress and tiredness than people who completed it on paper.
  • Perhaps, then, any discrepancies in reading comprehension between paper and screens will shrink as people's attitudes continue to change. The star of "A Magazine Is an iPad That Does Not Work" is three-and-a-half years old today and no longer interacts with paper magazines as though they were touchscreens, her father says. Perhaps she and her peers will grow up without the subtle bias against screens that seems to lurk in the minds of older generations. In current research for Microsoft, Sellen has learned that many people do not feel much ownership of e-books because of their impermanence and intangibility: "They think of using an e-book, not owning an e-book," she says. Participants in her studies say that when they really like an electronic book, they go out and get the paper version. This reminds Sellen of people's early opinions of digital music, which she has also studied. Despite initial resistance, people love curating, organizing and sharing digital music today. Attitudes toward e-books may transition in a similar way, especially if e-readers and tablets allow more sharing and social interaction than they currently do.

  • David Heckman, a mathematician, was accustomed to lecturing to the class, but he had to take on the role of a roving mentor, responding to raised hands and coaching students when they got stumped

  • That fall, with little debate or warning, it placed 4,700 students into computerized math courses. Last year some 50 instructors coached 7,600 Arizona State students through three entry-level math courses running on Knewton software. By the fall of 2014 ASU aims to adapt six more courses, adding another 19,000 students a year to the adaptive-learning ranks.
